ABSTRACT:
A device for producing intensity-modulated light over a broad frequency range comprising a frequency tunable light soruce, a control line for controlling the frequency of the light source to provide a first frequency at a first time and a second frequency at a second time, and an interferometer with a differential path length. The interferometer functions to recouple the light frequencies after propagating along different interferometer paths to effect a frequency beating. The resulting beat frequency is the intensity-modulated light.
